"hup! is an absolute game changer"

Laura Jane Clark

Leading architect & star of BBC's Your Home Made Perfect, hup! brand ambassador

People often ask how they can add an extension or rebuild their unusable conservatory in the most efficient way possible - hupl! is definitely the answer. Basework is usually the biggest minefield and the biggest headache for homeowners, so having something where you can use the existing base, and don’t need to start digging down and just build, getting watertight in two or three days, it's an absolute game changer.
